Application filed February 28, 1890. Serial N0. 342,037. (No model.)

, in Nail-Plate Feeders; and I do hereby de- 'to cause the feeding ofthe nail-plate.

clare that the following is a full, clear, and.

exactdescription of the same.

My invention relates to automatic nailplate feeders for nail-cuttingmachines; and the object of my invention is to arrange an automaticnail-plate feeder in such a manner that itmay be attached to theordinary handfeed machines at present in use, and thus obviate thenecessity of buildinga nail-cutting machine expressly to enable thenail-plate feeder to be used in connection therewith, which is the casewith most, if not all, of the automatic nail-plate feeders at present inuse; also, to make such other improvements in said nail-plate feeders aswill be hereinafter described and claimed. 1

In the drawings hereunto annexed, illustrating my invention, similarletters and unmerals of reference indicate like parts.

a is the frame-work of an ordinary nailcuttin machine carried on anyordinary support-s b.

c are the ordinaryprojections of the framework a, forming bearings tothe ordinary main shaft d, on the end of which is secured a disk Figs.11, 11, and 11 are Hill e, provided with a crank-pin f, which, by aconneeting-rod g, operates the lever 72. of the cutting-head 1',provided with cutter 7.1, being carried by the ordinary bearings Zin theprojections m of the frame a.

it is the ordinary rest, carrying the bed-cutter 0.

All the above mentioned parts are constructed and arranged as in theordinary handfed nail-cutting machines at present in use, and they arethe only ones with which my automatic nail-plate feeder connects it isnot considered necessary to show any of the remaining parts of suchordinary machine.

1 is a switch-cam (see Figs. 1, 2, and 16) se cured on the main shaft(Z. This is provided with a cam projection 2 for actuating a lever 3,hereinafter described.

4. is a slide-bar (see Figs. 1, 2, 2, 1S, and 19) carried in bearings 5and (5, attached to the projections c of the frame a. This slide-bar isprovided with an adjustable projection 7, secured thereto by bolts 8,passing through slotted holes 9 in the bar 1.

10 is a slotted opening formed with an enlargement 11 for holding a pin12, provided with a collar 13, adj ustably situated therein, beingsecured in the desired position in the slot 10 by a nut 14.

As the projection 7 travels from side to side in front of the bearing 5,it becomes neces sary to provide for this. Consequently the said bearingis formed as more particularly shown in Fig. 2, where this end of theslide-bar is provided with a groove 15, (see also Fig. 18,) into whichthe projection 16 of the bearing 5 enters, the parts being arranged, asshown, so that the projection 7 may freely travel over the top of thebearing 5,while it securely guides the bar 1.

18 is a head situated in and actuated by the groove 19 of theswitch-cam, the neck 17 of which is titted to an opening formed in theslide-bar -t and forms a bearing to the said neck, so that by therevolutions of the cam 1 the slide-bar &.is caused to slidelongitudinally from side to side of the machine, having a reciprocatingmotion.

20 is a bracket (see Figs. 1 and 2) attached to or made in one with oneof the projections m, as shown, carrying a lever 21, by a pivot 22. Theends 23 and 2101? this lever are both provided with a slot'openin g 25.(See Fig. 17.) The slot in the end 23 (see Fig. 18) connects with thepin 12 in the projection 7, and thus the motions of the slide-bar 4 areimparted to the lever 21.

20 and 27 are brackets attached 011 the frame a, carrying a slide-bar28. The bracket 26, as shown, (see Figs. 1, 2, 10, and 11,) is providedwith a cap 29, which is omitted in bracket 27, as it would obstruct themotion of the end 24 of the lever 21, which passes over it. This saidend of the lever is connected to the slide-bar 28 by a pin s, sliding inthe slotted end 21 of the lever 21, and thus the vibrations of the levercause a reciprocating longitudinal motion to the slide-bar 28. On theupper side of the slide-bar 28 are attached brackets 30, (see Figs. 10and 11,) made in the form of double eyes, in which are carried the pins31, provided with slot-openings 32 (see Figs. 11, 11, and 11) to receiveeach and hold the end of one'of the straps in the manner which will behereinafter more particularly described. The heads 31 ot the pins 31 aremade cylindrical and are provided with ratchet-teeth 35, also a squareprojection 36, by which with a key the pins 31 may be turned about inthe brackets 30.

37 are springs attached on the slide-bar 28 and arranged to act upon theratchet-teeth 35, so that when the straps have been tightened, for thepurposes hereinafter described, the said pins 31 will be held by thesprings 37 from rotating and slackening the straps.

Horizontally in the slide-bar 28 is formed a slotopenin g 38, in whichis placed a bolt and nut 39, thereby adjustably attaching to theslide-bar a vibrating link 40, the other extremity of which connectswith the main arm 41 of the toggle-joint hereinafter described.

To the under side of the frame a is attached a bracket 41 by means of aset-screw 42, which. forms a pivot, so that the bracket 11. maybeadjusted in position upon the said pivot and then firmly secured inplace, the

bracket being situated so that the cylinder 61 (hereinafter described asbeing carried by a frame 57, attached on the bracket) will be in theproper position to present the nailplate to be out by the cutters 7t.and 0, as shown in Figs. 1 and 2.

On the lower part of the bracket 11 is at taehed or made integraltherewith a bracket 13. To this is pivoted the main arm 44 of thetoggle-joint. (See Figs. 2, 10, 11., 22, 223, 21, 25, 20, and 27.) Inthe upper end of the main arm +1.1- a slot and recess 16 are formed toreceive an adjustable pin 15, provided with a collar and secured inplace by a screw-nut i7. \Vith the pin 45 the link 4-0 connects, so thatthe longitudinal reciprocating motions of the slide-bar 28 impartvibratory motion to the main arm 14, as indicated by dotted lines inFig. 10, which vibratory motions may be increased or diminished inextent to a certain amount according to the position that the pin 45 issecured in the slot 10.

49 is a bracket attached on the arm 44 by a pin 50 and tap-bolt 51, theformer of which forms a journal for the upper arm 52 of thetoggle-joint. This arm is provided atits lower extremity with an eye 53to fit the pin 50 and at its upper extremity with aball 51. By providingthe main arm etl with the slot 4-8 and by passing the bolt 50 andtap-bolt 51 through the said slot the position of the bracket 49 isrendered ad j ustablc.

On the upper portion of the bracket ll is secured a head 55. To this ispivoted at 50' a bent frame 57, having bearings 58 made integraltherewith. The caps 5.) of the said ITO bearings are preferably eachmade integral with a distance-bar 60, and by this said frame andbearings is carried the cylinder 61; which consists of a hollow sleeve(see Figs. 12, 13, 14, and 15) provided with collars 62 and 63, closelyfitting the said bearings of the frame, so that no appreciable end-playof the cylinder will be allowed. The cylinder proper 61 terminates in aconical flattened hollow projection 64,to which are attached side guidesby bolts and nuts 66. i

67 are projecting flanges formed on the hollow projection 64:. To thesethe necks of the guides 65 are fitted, so that by slackening the bolts66 supplementary pieces may be placed between the necks of the guides 65and the hollow projection 641. Thus the distance that the guides 65maybe set apart maybe adjusted to certain different widths ofnail-plates froiii which the nails are cut, as the guides 65 guide thenail-plate edgewise in the ordinary manher for nail-plate feeders ofthis class.

011 the upper and lower sides of the projection 6st are attached, bymeans of plates and clamping-bolts 68, spring-bars 69, which hold thenail-plate 7 0 to the proper vertical elevation in a line with the axisof the cylinder 61. By the grip of the spring-bars 69 upon thenail-plate it is prevented from returning forward after it has been fedbackward, as will be hereinafter more particularly described.

. To the cylinder 61, by means of a clamp ing-plate 71 and bolts, asshown, are secured the ends of the straps 33. These are turnedsufficiently round the cylinder 61 and their opposite ends connectedwith the pins 31 by (passing them through the slots 32, (see Fig.

11 and cutting small slits 72 'in the straps and turning up .the flaps73 thereby formed the ends of the straps are prevented from withdrawingfrom the slots 32. The straps may be wound up on the pins to bring themto the proper tension and properly time and set the rotations of thecylinder 61, which will be caused by the reciprocating longitudinalmotions of the slide-bar 28.

As shown in solid lines in Fig. 10, the slidebar 28 is in the midwayposition or at halfstroke. )Vhile the motion of the bar 28 is thuscausing the rotation of the cylinder 61 it is also operating thetoggle'joint, causing it to raise and lower the frame 57. The ball 54 ofthe arm 52 is received in a socket 74, formed in the frame 57.

75 is a retaining-plate attached on the side of the frame 57. It isprovided with a slotopening 76, (see Figs. 10, 28, and 29,) throughwhich the arm 52 passes. This retainingplate is for the purpose ofretaining the ball 54 and socket 7 & together should they be inclined topart by reason of the machine being run at a high speed.

To cause a more steady motion of the frame 57 and cylinder 61 carried byit, a parallel tongue 77 is formed on the frame 57,projecting downward.This is received within the parallel slot 78 of a bracket 79, formed onthe bracket 41 or attached thereto, as desired. (See Figs. 2, 30, and31.)

Returning to the head 55, it is provided with an arm 80, made integraltherewith, and integral with the top of this arm is formed the slide-bed81 of the mechanism A, by which the feeding of the nail-plate to thecutters 7c and 0 is caused. This mechanism Ais more particularly shownby Figs. 3, 4, 5, 6, 7, 8, and 9. The slide-bed 81 consists of a groovedplate, of which 82 is the groove. In this the slide 83 moves, beingguided by the upwardeXtending sides 86. The bed 81 is provided with anopening or recess The slide 83 is made integral with a flange 85, andthis flange slides over the sides 86 of the bed 81. It is provided withan opening 87 (hereinafter more particularly described) and an upwardintegral projection 88. 9% is a projection formed on the flange 85, theobject of which is to carry the handle a at such a height that theferrule a will not be caught on any of the parts of the mechanism Abefore it comes to the plates 98, as will be hereinafter described.

On the lower side of the slide 83 a downward-projecting. arm 89 isformed integral therewith. To this is hinged at 90 an upward-projectingarm 91, the two (89 and 90) being recessed, as shown in Fig. 9, to. giveroomfor securing a spring 92, as shown, (see Fig. 7,) held in place by atap-bolt 93, the said spring being arranged to press the arm 91 apartfrom the projection 89. The arm 91 extends up through the opening 87,which is much wider, as shown by the dotted lines 95 and 96 in. Fig. 7,allowing for the required motion of the arm, and this opening 87, asshown in Fig. 3, is of equal width with the arm. 91, allowing for itsfree motion.

To the projection 88 and arm 91 are attached by tap-screws 97 plates 98.)Vhen the slide 83 is put in proper position with the bed 81, theprojection 89 and arm 91 project down'through the opening or recess 8i,it being made sufficiently wide to allow of the necessary motion of theslide 83.

The slide is secured in place in the bed 81 by a strap 99 in front andbolts and nuts 100, the partsbeing fitted to allow the slide 83 to movefreely longitudinally, but without lost motion transversely. The backend of the slide is held in place bya strap 101 and bolts and nuts 102.This strapfls provided with a recess in which is placed an elasticcushion 103, and under the elastic cushion and about the strap, asshown, Figs. 3, 4, 5, and 6, is placed a gib 104, so that by properlytightening down the strap 101 by the bolts and nuts. 102 an adjustableamount of friction may be imparted to the slide 83. By this adjustablefriction on the slide 83 a much smoother action of the slide isobtained, and, if desired, the strap 99 may be similarly provided withan elastic cushion and gib, as described for the strap 101; but in themost of cases one adjustable friction will be found sufficient.

To the bed 81 is attached a strap 105 by bolts 106. This is providedwith a set-screw 107, (secured by a jam-nut 108,) adapted to regulatethe amount that the slide 83 will move forward by means of a spring 100,and thus govern the amount of feed travel that will be imparted by theslide 33 and gripping-plates 98 to the handle 0., as any excess ofmotion of the spring-bar U will only cause the pawl a to swing fartherforward in the are a. (See Fig.

The spring 109, as shown in Fig. 2, is illustrated as a bow-springattached on the arm 80, and is arranged to press directly against thearm 91 and projection 89; but, as shown in Figs. 3 and 4, it consists ofa spiral spring connected upon a hook 110, projecting below the flange85 and secured thereto, and a projection 111, secured on the under sideof the bed 81, provided with an arm terminated in a hook 112,the springbeing arranged to draw the two hooks 110 and 112 with some force towardeach other, thus causing the front end of the slide 83, when nototherwise acted upon by the spring-bar b through the pawl a, to restagainst the end of the set-screw 107.

113 is a pivot by which is attached to the flange 85 the pawl a,situated as shown in Figs. 3, 4, and 7, and in outline in Figs. 1 and 2this is fitted to allow the pawl a to swing freely, and by beingprovided with a countersunk head can be arranged to take up any lostmotion or looseness of the pawl a. It is screwed into the flange 85, andits end projecting below the flange is provided with jam-nuts to secureits position. (See Fig. 4.) The pawl a actuates the arm 91 and causesthe plates 08 to grip the handle a of thenailplate-holding tongs, sothat when the slide 83 is caused to move backward the handle a will movewith it and cause the nail-plate to be moved farther down in thecylinder 61 and project at each rotation of the cylinder the amountnecessary for forming the next nail to be cut off by the cutters 7t ando.

The tongs attached to the handle a are of the ordinary description atpresent in use, and are not therefore shown, being part and parcel ofthe handle." They are furthermore made sufficiently small to pass freelywithin the cylinder 61 in the same manner as heretofore in use in thisclass of rotatingcylinder automatic nail-plate feeders.

The handle a is provided with a ferrule a. Is so adjusted in itsposition on the handle that by coming in contact with the plates 98 thehandle is prevented from moving the tongs too far down in the cylinder01 and prevents them from coming in contact with the cutters o and 7:,(see Fig. 2,) by which the nails are cut.

The action of the plates 98 to grip the bandle o and release it iscaused in the following manner by the parts now further described:

split pin 1).

The cam projection 2 of the switch-cam 1 actuates the lever 3, pivotedupon a pivot, bar, or shaft Z), projecting from one of the projections cor extending between the two projections c, as found most convenient.The lever 3 is provided with a downward-extending arm 11*, pressed uponby a spring I) to cause the lever 3 to return forward after it has beenforced backward, as shown in Fig. 2, by the cam projection 2. The upperend of the lever terminates in a double eye I), to which is attached theback end of the spring-rod I). (See Figs. 1, 2, 20, and 21.) The frontend of this rod is bent and passed through an eye 1), formed in the endof the pawl a, being secured by a washer b and The red I) is adjustablein length, being made in two parts provided with right and left handscrews united by a correspondingly-screwed buckle 0 secured by jam-nuts0 To cause a certain amount of spring in the length of the rod tolengthen and shorten the same, it is provided with a bent portion 0.\Vhen the cam projection 2 begins to move the lever 3 to the positionshown in Fig. 2, the rod If first moves the eye U in the are a (seeFig.3) until the handle a of the tongs is firmly gripped by the plates98 by reason of the pawl a pressing upon the arm 91, the eye I) beingbrought to about the position of the dotted line a, the cam projection 2continuing to move the lever 3 and rod U. The slide 83, with partsthereunto attached, is new compelled to move in the bed 81 from theposition shown in Figs. 3 and 4. to the position shown in Figs. 1 and 2,the resistance of the spring 100 and friction-bearing being overcome bythe motion of the rod If, whereby the nailplate is moved backward theamount required to be cut off to form the next nail. This operation isso timed that it takes place just before the cutter 7c operates, andjust when the cylinder has completed one of its half-revolutions, thecam projection 2 being so configurated that the parts are positivelyheld in position while the cutting off of the nail is accomplished. Assoon as the cam projection 2 has passed. thelever 3 the spring 0 causesthe red I) to return the pawl a from the position shown in Figs. 1 and 2to that shown in Figs. 3 and t. The spring 92 now causes the plates 98to release the handle a, and the spring 100 now moves forward the slide83 and parts thereto attached to cause the front end of it to restagainst the end of the set-screw 107, ready for the next backward orfeed motion.

The amount that the toggle-joint will raise and lower the frame 57 andcylinder 01, as represented by the dotted line at in Fig. 2, can be adjusted by the hereinbefore-described adjustment of the parts of thetoggle-joint. The pivot 50 being placed at a lower level than that ofthe end of the projection (54, (see Fig. 2,) the cylinder 61 is causedto move bodily forward as it is raised upward. By

adjusting the position of the pin 12 (see Figs. 1, 18, and 19) in theslot 10 the vibrations of the lever 21 may be enlarged or decreased inextent, and thus the longitudinal motions of the slide-bar 28 may beadjusted to impart to the cylinder 61 and parts thereto attached aneXact semi or desired rotation.

By the spring part c of the bar b any undue strain upon the partsoperated thereby is prevented should they get out of perfect adjustment, and the said spring part 0 also insures a more even or equalaction of the parts operated by the said rod.
